ARCS - Admiralty Raster Chart Service


ARCS is the world's leading electronic raster chart service. ARCS complements the British Admiralty (BA) paper chart series to provide first-class electronic navigation that greatly improves safety.

ARCS charts are exact digital copies of the world-leading BA paper charts. All ARCS charts have the same familiar appearance and use the same internationally recognised symbology as the Admiralty paper chart series. Their instantly recognizable image aids the transition to electronic navigation by minimising training requirements and enabling your crews to navigate with confidence.


Global Coverage

Over 3000 ARCS charts provide official, global coverage of the world's commercial shipping routes, with extensive coverage of main ports and harbours at a wide range of scales.

Maximum Flexibility

ARCS comes complete with a comprehensive weekly update service and is available on annual subscription. Coverage is licensed on a chart by chart basis to give you maximum flexibility. You only access, and pay for, the charts you require. Instant access to additional charts can be quickly and easily obtained in emergency situations via phone, fax or e-mail.

ARCS charts are also available in regional and world folios to give you greater coverage at substantial cost savings.

Latest Chart Updates Applied in Seconds.

ARCS service includes a fully automated update service.

Updates include all New Editions and Replacement Charts and both Temporary and Preliminary Notices. This easy to follow ARCS update procedure ensures your vessel's entire ARCS chart folio can be corrected in just a few seconds.

Proven Benefits

ARCS high quality digital image and full geographical referencing ensure superior chart display and maximum benefits in both real-time navigation and passage planning.


Safer Navigation

ARCS charts can be fully integrated with Global Positioning System (GPS). Vessel position, course and speed can be automatically plotted and updated as frequently as once a minute to give far greater positional accuracy than with traditional methods of navigation. User-defined overlays of danger areas, waypoints, notes, offset and check bearings can also be manually input and stored for all relevant charts.

ARCS real-time vessel positioning and overlay facilities provide considerable real-time navigational benefits and greatly reduce the risk of grounding.

Improved Siturational Awareness

Radar targets can be superimposed over ARCS charts to show actual distance and direction to other vessels and obstructions, providing an instant overview of your current situation. When used in conjunction with radar to provide collision avoidance indicators and alarms, ARCS significantly improves safety of navigation, and is particularly important in busy or confined waters.

Time Saving

Routes can be quickly and efficiently planned in advance and stored for future, repeat use. Passage plans can be easily adjusted at any time. Bearing and Distance between waypoints are automatically calculated. Planned routes are automatically applied across all chart scales to substantially reduce time spent at the planning stage.

Traditional Techniques

ARCS also enables the use of traditional techniques such as dead reckoning (DR) to verify GPS signal or in the event of GPS unavailability.
